IMPROVEMENT IN SPRINGS FOR VEIIIQLES.

Specification forming part of Letters Patent No. 139,809, dated June 10, l87`3 g `application filed October 8, 1872.

To all whom it may concern:

Be it known that I, PETER PENN, of Cleveland, county of Cuyahoga and State of Ohio, have invented an Improvement in Elliptic Springs,`of which the following is a specilication:

This improvement consists in the arrangement of a clip, embracing the leaves of the spring in such a manner that the leaves cannot slip sidewise or become separated. They also render it unnecessary to pierce but one leaf of the spring, so that the spring isV not weakened as in the ordinary method of punching and beading the leaves; and this constitutes an important feature of my invention, as it does away with the slots and bead, which weaken the spring and are liable to become so much worn as to be useless.

The following is a description of its construction and operation:

Referring to the drawing, Figure 1 is a perspective view of a spring having my improvement attached. Fig. 2 is a detached view of two forms ofthe above-mentioned clip.

A A are the leaves of an ordinary elliptic spring, bolted together at the middle. B B', Fig. 2, Mis a clip for placing on the spring to prevent them slipping. The usual `manner ot' doing this is to cut or punch slots near the ends, in each leaf, and press up a bead to play in said slots; but this is objectionable, because the cutting or punching weakens the meta-l, and does not prevent the leaves from being separated or lifted up from one another at the ends. The clips B overcome these objections. They are cast in malleable iron, and` may pass entirely around the leaves,"as seen at B, Fig. 1,lor may pass around three sides only and have the ends turned under, as at B, Fig. l. On the inside of the clip is casta rivet, `b,for securing it to one ofthe leaves. The clip is secured to the next to the uppermost leaf by riveting it near the end of said leajf, and embraces-all the without the usual beads and slots, all as set forth.
